Benefits of technology
The present technology is about improving respiratory medical devices used for diagnosis, treatment, or prevention of respiratory disorders. The aim is to enhance the comfort, cost, efficacy, ease of use, and manufacturability of these devices. The methods and systems described herein can improve the functioning of a processor, such as a specific purpose computer, respiratory monitor, or a respiratory pressure therapy apparatus. Additionally, the technology advancement can facilitate automated management, monitoring, and treatment of respiratory conditions, including sleep disordered breathing. The improvements can enhance the detection of sleep stages compared to other methodologies.
Problems solved by technology
It often causes excessive daytime somnolence, and it may cause cardiovascular disease and brain damage.
Treatment of OSA by CPAP therapy may be voluntary, and hence patients may elect not to comply with therapy if they find devices used to provide such therapy one or more of: uncomfortable, difficult to use, expensive and aesthetically unappealing.
For other forms of therapy, such as the delivery of oxygen, the patient interface may not include a seal sufficient to facilitate delivery to the airways of a supply of air at a positive pressure of about 10 cmH2O.
However, air pressure generators for medical applications have particular requirements not fulfilled by more generalised air pressure generators, such as the reliability, size and weight requirements of medical devices.
Delivery of a flow of air without humidification may cause drying of airways.
While RPT devices may typically be configured to detect SDB events such as apneas and hypopneas in real time, they do not typically determine or provide more detailed information about the patient's sleep while on respiratory pressure therapy.
However, such calculation tends to underestimate the AHI, since for significant periods during the session the patient may not have been asleep.
The result is that a patient or clinician tends to get an overly optimistic picture of the efficacy of the patient's therapy if conventional AHI calculation is employed.
However, inferring sleep stage purely from respiratory flow rate has proven to be a difficult task, with consequent effects on the accuracy of AHI calculation and hence AHI-based monitoring of patients on CPAP therapy.

Methods and apparatus infer or indicate sleep stage(s) of a patient from a respiratory flow rate signal of the patient. The method may include applying a plurality of detection pathways to a signal representing a respiratory flow rate of the patient, wherein each detection pathway is configured to generate start events and end events indicating start times and end times of episodes respectively of a corresponding sleep stage, wherein each start event and each end event has a priority; and combining the start events and end events based on their priorities to produce an indication of the sleep stage of the patient. The apparatus may include a sensor configured to generate a signal representing a property of a flow of air within a patient interface; and a processor configured to implement a method of inferring a sleep stage of the patient from the signal.
